People who have Type O blood can are called universal donors.
The question seem to be incomplete but I found the complete question which is:
If you are performing this test on an unknown organism, why is it a good idea to run simultaneous tests on known phenylalanine-positive and phenylalanine-negative organisms?
Here is the Answer:
Inoculation of a positive control and success from it includes certainty to negative outcomes on an unknown organism. That is, you know the test is working effectively, so the negative outcome is most likely precise. Without the positive control, there is dependably a component of uncertainty whether the negative outcome is a genuine negative or a false negative. performing the test on a known phenlalanine-negative organism is valuable in that it exhibits what a negative outcome looks like.
Genes are a unit of heredity that is transferred from a parent to the offspring and is held determine some characteristics of the offspring. Some genes include: the color of the eyes (whether you have your mother's or father's eyes) the hair color, and skin color.
Inherited traits means you received something from your parents, grandparents or other family members.
Acquired traits means a characteristic or trait that produces a phenotype that is a result of an environmental influence.Acquired traits are not coded for in the DNA of an individual and therefore cannot passed down to offspring during reproduction. <span />
